Greetings Maria.
Most of the outrageous claims put forward by these articles are pure folly. They are mere fabrications and vain imaginings of atheistic pseudo-scientists. All of us should strive to unlearn the plethora of falsehoods that we have been constantly subjected to from our youth.
It starts with familiarizing ourselves with the cosmological paradigm presented to us by Sacred Scripture, in light of the consensus view of Holy Church.
Let's start with a few basics. You mentioned something about "perhaps mankind would someday discover life on other planets with a solar system much like our own."
To begin with, the earth is not a planet, and the Holy Fathers in their writings do not refer to Earth as a planet. They do speak in terms of the sun being a planet, since planet means to wander, hence for something to be a planet, it has to be in motion. The notion of the earth as a planet only began to gain acceptance in the 17th century, among the pseudo-scientists.
The Divine Scriptures and the Holy Fathers, in harmonious accord with one another, speak in terms of the earth being motionless, not rotating on its axis, at the center of the universe.
The Holy Fathers never entertained absurd notions of life on "other planets" [sic], or billions of solar systems. This is all completely preposterous and nonsensical and an obvious philosophical fabrication embraced by modern pseudo-science.
In the 8th century writings of St. John of Damascus in the East, and St. Bede in the West, both state that the moon and stars derive their light from the sun, and do not possess their own power of giving forth light. So it is by no means proven or established that there are billions of suns out there similar to our own, as they would have us believe.
